887 SECTION 803 – SODDING DESCRIPTION
803.01Description
This work consists of furnishing and placing sod at the locations show n on the Plans or where directed by the Engineer. Ordinarily, this work will consist of furnishing and placing new sod originating from sources outside the right -of-way. In some cases, however, the work will include removing sod from areas where the requi rements of the improvement would destroy existing sod, storing the sod so removed, and resetting it in areas shown on the Plans or designated by the Engineer. MATERIALS
803.02Sod
Provide new sod consisting of live, dense, w ell-rooted growth of permanent grasses, free from Johnson grass, nut -grass, and other 803.02
888 undesirable grasses or weeds, that is well -suited for the intended purpose and for the soil in which it is to be planted. Correct installed sod that does not meet these requirements as directed by the Engineer and at no additional cost to the Department. Cleanly cut all sod in strips having a reasonably uniform soil thickness of not less than 1 inch and a reasonably uniform width of not less than 8 inches and a length of not less than 12 inches.
The sale or movement of turf grass or sod for propagation is controlled by Tennessee Plant Pest Act of 1955, TCA 43 -515, et. seq. It requires inspection during the growing sea son and authorization by the Tennessee Department of Agriculture prior to removal. The authorization may be certificates for “Tennessee Certified Premium” sod, or “Tennessee Certified” sod. If the sod offered for use will not meet the requirements for certified sod but will meet the requirements of this Subsection, obtain a “Permit for Movement of Non -certified Turf Grass Sod.” Request the inspection from the Tennessee Department of Agriculture as early as possible to avoid undue delay. Include the follo wing information in the request for inspection:
seller,
Direct the request for inspection to the following address: Division of Plant Industries Tennessee Department of Agriculture, Ellington Agricultural Center Melrose Station 40627 Nashville, Tennessee 37204 Telephone (615) 360 -0130 Furnish a copy of the Department of Agriculture authorization to the Engineer before removing any sod. 803.03

803.04Ammonium Nitrate
Provide ammonium nitrate conforming to 918.03.
803.05Agricultural Limestone
Provide agricultural limestone conf orming to 918.04.
803.06Reserved
CONSTRUCTION REQUIREMENTS
803.07Weather Limitations
Set or reset sod only when the soil is moist and favorable to growth. Do not perform any setting or resetting between December 1 and February 1, unless weather and soil conditions are considered favorable and permission is granted by the Engineer.
803.08Removing and Storing Sod for Resetting
Cut, handle, and store sod removed from such areas as lawns, yards, and lots so that the sod can be reset in the same locations from which it was removed. Do not substitute sod unless approved by the Engineer . Unless resettings od immediately after cutting, stack the sod in piles, and keep it moist until reset. Reset sod within 7 days after removal, unless otherwise approved by the Engineer.
803.09Sodding
Bring the area to be sodded to the lines and grades shown on the Plans. Unless otherwise directed by the Engineer, place topsoil as specified in
203.06before placing sod. When laying sod adjacent to structures, ditch
paving, sidewalks, and similar features, ensure that water will not pond and will flow as designed. Loosen the surface of the ground to be sodded to a depth of not less than 1 inch with a rake or other device. If necessary, sprinkle 803.10
890 the ground until saturated for a minimum depth of 1 inch, and keep moist until the sod is placed. Immediately before placing the sod, apply fertilizer and lime uniformly to the prepared surface of the ground. Apply fertilizer at the rate of 12 pounds of Grade 10 -10-10, or equivalent, per 1,000 square feet. Apply agricultural limes tone at the rate of 100 pounds per 1,000 square feet. Place sod as soon as practicable after removing from the point of origin and keep it in a moist condition during the interim. On urban projects, place the sod on all newly graded cut and fill slopes as work progresses to prevent damage to adjacent facilities and property due to erosion. Take care to retain the soil on the root system during excavating, hauling, and planting. Ensure that all sod is in an acceptable condition upon delivery and placement at the work site. Do not use sod damaged by heat or dry conditions. Carefully place the sod by hand on the prepared ground surface, with the edges set in close contact and, as far as possible, in a position to break joints. Lay and fit each strip of sod into place, thoroughly wet it, and roll with an approved roller or hand -tamp, as approved by the Engineer. On slopes of 2:1 or steeper, pinning or pegging may be required to hold the sod in place.
803.10Period of Establishment
Provide all labor and arrange for all watering necessary for rooting of the sod. If rainfall during the first 14 days of the period of establishment is inadequate to maintain a moist soil, perform the necessary watering, as approved by the Engineer. After 14 days, apply ammonium nitrate at the rate of 3.5 pounds per 1,000 square feet and re -water the sod.
An authorized representativ e of the Department will conduct an inspection to determine the acceptability of the sodding no less than 90 days but not more than 150 days after completion of the sod work or at the acceptance of the entire Project, whichever is later, except that the Engineer may delay the inspection when conditions are such that the acceptability of the sodding cannot be determined at the end of the 150 - day period or at the time the entire Project is accepted. 803.10
891 C. Contractor Guarantee The Contractor shall guarantee, at th e time of the Department inspection, a minimum of 95% live sod on the sodded areas and that there are no vacant areas of dead sod larger than 100 square feet. This guarantee shall apply to all permanent sodding performed in conjunction with the Project, regardless of the type protection used or the season in which the sodding is performed.
When the sodding does not meet the guarantee requirements at the time of inspection, repair the defective areas . Required repairs may include preparing the sod bed, refertilizing, resodding, and providing any erosion control items that were originally required. Perform such work as soon as favorable working conditions occur after being advised of the repairs required. The Department will not pay for the repair work and materials required to fulfill the guarantee requirements.
From the time sodding and protection work begins until the date the entire Project is accepted, keep all sodded areas in good condition at all times. Do not allow placement of any equipment or material on any planted area, and erect suitable barricades and guards to prevent equipment, labor, or the public from traveling on or over all areas planted with sod. Promptly repair damage to sodded areas as directed by the Engineer. Perform all work and provide all materials necessary to protect, maintain, and restore sodded areas during the life of the Contract at no additional cost to the Department, except for additional work caused by Department -requested changes. If it becomes necessary to disturb previously sodded areas due to slope changes, addition of paved ditches not previously located by the Engineer, or other changes made at the direction of the Engineer, the Department will make payment for a reasonable amount of additional work, as determined by the Engineer, at the original contract unit prices. The Department will not pay for additional work due to changes made for the benefit of the Contractor, such as slope changes to obtain balance excavation instead of borrow excavation, nor will the Department pay for addi tional work required because the Contractor failed to properly coordinate its erosion control 803.11
892 schedule thus causing previously sodded areas to be disturbed by operations that could have been performed before sodding.
If, on Contracts involvi ng sodding and other items of construction, the other items have already been completed, the time required for establishment under this item will not be charged against the time stipulated in the Contract for completion of the Project.
803.11Disposal of Surplus Material
Dispose of all surplus material as directed by the Engineer. COMPENSATION
803.12Method of Measurement
The Department will measure:
distributors, or accurate water meters. Only areas upon which sod has been set or reset will be measured for payment.
803.13Basis of Payment
The Department will pay for accepted quantities, complete in place, at the contract prices as follows: Item Pay Unit Sodding (New Sod) Square Yard The Department will pay for water applied during the first 14 days after sodding work is complete, including the water used in the re -watering of the sod after the applic ation of the ammonium nitrate, at the contract unit price for Water per M.G. (1,000 gallons). Water applied after this period will not be paid for and will be considered incidental to other items. 805.01
